SUMMARY OF INVENTION Technical Problem

In a packing tool in the related art, when a significant impact force such as collision from dropping is applied to an outer box, since only a cushioning operation of a cushion film is basically applied to a product cushion, the cushioning operation may be insufficient depending on a product.

Moreover, due to the circumstances in which the product is restrained and held in a state of being clamped between a pair of the cushioning films, a restraining force of the cushioning films in a surface direction with respect to the product is not particularly significant. Therefore, when a significant impact force such as collision from dropping is applied to the outer box, the product inside the outer box may move to an outer side (the frame member side) where the impact force is significant, along the surface direction of the cushioning film so that the cushioning films may not be able to sufficiently exhibit the cushioning operation.

Therefore, in the packing tool in the related art, it is difficult to mention that cushioning performance against an impact force is sufficient, and there is room for improvement regarding the above-described point.

The present invention has been made in consideration of the above-described circumstances, and the main challenge thereof is to provide a convenient packing tool having high cushioning performance by rationally improving a packing method.

Solution to Problem

According to a first characteristic configuration of the present invention, there is provided a packing tool including a pair of support frames that has a recessed section in which a packing object is able to be arranged and a support portion which has a cushioning function to support the packing object arranged in the recessed portion on the central front surface side, an outer box that is able to accommodate the pair of support frames in a posture in which the front surfaces of the support frames face each other, and an inner bag that is freely mounted in at least one of the support frames in a state where the packing object is inner-packed and is able to cause the packing object inner-packed in a mounting posture with respect to the support frame to be subjected to position-holding within the recessed section of the support frames.

In other words, according to the configuration, the packing object can be accommodated in the outer box in a state where the packing object is subjected to position-holding within the recessed section of the pair of support frames by using the inner bag and a state where the packing object is supported by a support portion of the pair of support frames.

Therefore, when a significant impact force such as collision from dropping is applied to the outer box, a position-holding operation performed by the inner bag can prevent the packing object from moving to an outer peripheral side (the support frame side) where a collision force is significant. At the same time, a cushioning operation performed by the support portion can be applied thereto. According to the synergy effect thereof, it is possible to exhibit high cushioning performance.

According to a second characteristic configuration of the present invention, there is provided a packing tool including a support frame that has a recessed section in which a packing object is able to be arranged, an outer packing body that is able to accommodate the support frame, and an inner bag that has an inner packing space between an upper covering portion and a lower covering portion. The inner bag is configured to be freely mounted in the support frame in a mounting posture in which the packing object inner-packed in the inner packing space is subjected to position-holding within the recessed section in a state where the upper covering portion and the lower covering portion are spread over the recessed section of the support frame and the periphery of the recessed section.

In other words, according to the configuration, the inner bag can be mounted in the support frame in the mounting posture in which the upper covering portion and the lower covering portion are spread over the recessed section and the periphery of the recessed section, and the packing object can be subjected to position-holding within the recessed section of the support frame by the inner bag in the mounting posture thereof. In this manner, the packing object can be accommodated in the outer packing body in a state where the packing object is subjected to position-holding within the recessed section by the inner bag.

Therefore, when a significant impact force such as collision from dropping is applied to the outer packing body, a position-holding operation performed by the inner bag can prevent the packing object from moving to the outer peripheral side where the impact force is significant.

According to a third characteristic configuration of the present invention, the inner bag is configured to freely change the posture between an insertion posture allowing the packing object to be inserted into the inner packing space and the mounting posture, and is configured to change the posture from the insertion posture to the mounting posture as the tensile force with respect to the peripheral side of the recessed section is applied to the upper covering portion and the lower covering portion.

In other words, according to the configuration, when the inner bag is in the insertion posture, the packing object can be easily inserted into the inner packing space of the inner bag. As tensile force toward the peripheral side of the recessed section is applied to the upper covering portion and the lower covering portion, the posture of the inner bag can change from the insertion posture to the mounting posture. Accordingly, the packing object can be subjected to position-holding within the recessed section of the support frame by the inner bag in the mounting posture.

Moreover, since the upper covering portion and the lower covering portion of the inner bag are in the tensile state, when the packing object inner-packed in the inner bag tends to move due to drop impact or the like, movement resistance can be applied to the packing object in a state where the inner bag in the tensile state is pulled further. Accordingly, when a significant impact force such as collision from dropping is applied to the outer packing body, it is possible for the inner bag to more effectively prevent the packing object from moving.

According to a fourth characteristic configuration of the present invention, there is provided a packing tool further including a pair of the support frames in each of which the recessed section is arranged on the front surface side. The pair of support frames are configured to be freely accommodated in the outer packing body in a posture in which the front surfaces thereof face each other. The mounting posture of the inner bag is set to a posture in which the packing object is subjected to position-holding within the recessed section of each of the pair of support frames in a state where the upper covering portion and the lower covering portion are spread over the recessed section of each of the pair of support frames and the periphery of the recessed section.

In other words, according to the configuration, the inner bag can be mounted in the mounting posture of spreading over the recessed section and the periphery of the recessed section in each of the pair of support frames with respect to the pair of support frames in the postures in which the front surfaces thereof face each other. The packing object can be subjected to position-holding within the recessed section of each of the pair of support frames by the inner bag in the mounting posture. In this manner, the packing object together with the pair of support frames can be accommodated in the outer packing body in a state where the packing object is subjected to position-holding within the recessed section of each of the pair of support frames by the inner bag.

According to a fifth characteristic configuration of the present invention, the support frame is provided with a support portion that has a cushioning function to support the packing object which is arranged within the recessed section.

In other words, according to the configuration, not only is the packing object subjected to position-holding within the recessed section but also the cushioning operation performed by the support portion can be applied thereto. According to the synergy effect thereof, it is possible to exhibit high cushioning performance.

According to a sixth characteristic configuration of the present invention, the support portion is configured to include a support piece which is protrudingly formed in an edge portion of the recessed section of the support frame and is freely bent.

According to the above-described configuration, the support piece which is protrudingly formed at the edge portion of the recessed section can be applied to multiple types of the packing objects having shapes different from each other by being subjected to bending deformation in a state of being folded inside the recessed section on the bottom side depending on the shape of the packing object.

Moreover, when an impact force such as collision from dropping is applied to the outer box or the outer packing body, as the support piece is subjected to additional bending deformation from the posture in which the support piece is folded inside, the impact force transmitted to the packing object can be cushioned. Thus, cushioning performance can be enhanced further.

According to a seventh characteristic configuration of the present invention, at least a portion of an outer edge line of the inner packing space in the inner bag is configured to be positioned within the recessed section of the support frame in a state where the packing object is inner-packed and is mounted in the support frame.

In other words, according to the above-described configuration, since at least a portion of the outer edge line of the inner packing space in the inner bag is positioned within the recessed section of the support frame in a state where the packing object is inner-packed and the inner bag is mounted in the support frame, the inner packing space itself is prevented from moving out of the recessed section by the amount of the portion thereof. Therefore, a packing object inside the inner packing space can be further prevented from moving out of the recessed section of the support frame.

Therefore, when a significant impact force such as collision from dropping is applied to the outer box or the outer packing body, the inner bag can effectively prevent the packing object from moving to the outer peripheral side (the support frame side) where a collision force is significant. Thus, cushioning performance can be enhanced further.

According to an eighth characteristic configuration of the present invention, the recessed section is formed on a central front surface side of the support frame. Flaps which are freely folded toward a front surface side or a rear surface side are formed in two side portions facing each other in outer peripheral side portions of the support frame. The packing tool further includes an attachment portion for respectively attaching two side portions facing each other in outer peripheral side portions of the inner bag and the two flaps. The inner bag is configured to be mounted in the support frame in a state where the inner bag is pulled by a pair of the flaps by folding the flap toward the rear surface side from a state where the attachment portion attaches the side portion of the inner bag to the flap which is in a posture protruding toward the front surface side or the laterally outward side with respect to each set of the side portion of the inner bag and the flap of the support frame.

In other words, according to the configuration, the inner bag can be mounted in the support frame in a state where the inner bag is pulled by the pair of flaps by performing a simple operation in which the attachment portion attaches the side portion of the inner bag to the flap which is in a posture protruding toward the front surface side or the laterally outward side with respect to each set of the side portion of the inner bag and the flap of the support frame and the flap is folded toward the rear surface side from a state thereof.

Then, since the packing object can be arranged at a predetermined position within the recessed section of the support frame by the inner bag which is pulled by the pair of flaps from both sides, an expected cushioning operation performed by the support portion which supports the packing object arranged within the recessed section is reliably obtained.

Moreover, since the inner bag is in the tensile state, when the packing object inner-packed in the inner bag tends to move due to drop impact or the like, movement resistance can be applied to the packing object in a state where the inner bag in the tensile state is pulled further. Accordingly, when a significant impact force such as collision from dropping is applied to the outer box or the outer packing body, it is possible for the inner bag to more effectively prevent the packing object from moving to the outer peripheral side (the support frame side) where a collision force is significant.

Therefore, while the inner bag can be easily mounted in the support frame, cushioning performance can be enhanced further.

According to a ninth characteristic configuration of the present invention, the flap is configured to form a leg portion of the support frame in a posture being folded toward the rear surface side.

In other words, according to the configuration, since the flap for mounting the inner bag in the tensile state is configured to be used as the leg portion of the support frame as well (the leg portion for holding the posture in an accommodation state or non-accommodation state with respect to the outer box or the outer packing body), efficiency of the structure can be achieved compared to a case where the flap for pulling the inner bag and the leg portion for holding the posture of the support frame are separately configured, for example.

According to a tenth characteristic configuration of the present invention, the attachment portion is configured to include a bag-like hooking portion which is able to be hooked over the flap and is formed integrally with the side portion of the inner bag.

According to the above-described configuration, since the bag-like hooking portion is formed integrally with the two side portions facing each other among the outer peripheral side portions of the inner bag, the inner bag can be simply attached to the flap by causing the bag-like hooking portion to cover the flap and to be hooked thereover.

Therefore, attachment work of the inner bag can be facilitated and the efficiency of the structure can be further achieved.

DESCRIPTION OF EMBODIMENTS First Embodiment

FIGS. 1 and 2 illustrate a packing tool T which is used for packing a precision instrument A (an example of a packing object) such as an audio device and a monitor, for example. The packing tool T is formed to include a pair of upper and lower support frames 1 which have the same shape as each other, an outer box 2 which can accommodate both the support frames 1, and an inner bag 3 in which the instrument A can be inner-packed.

The support frames 1 are formed of pattern paper such as corrugated paper. Each of the support frames 1 is configured to have a rectangular recessed section 5 which is formed in an open manner so as to arrange the instrument A on a central front surface side of a rectangular base portion 4, and flaps 7 which are protrudingly and respectively formed in outer peripheral side portions of the base portion 4 so as to be freely folded toward a front surface side and a rear surface side.

As illustrated in FIGS. 1 and 2, in postures being folded toward the rear surface side, the flaps 7 function as leg portions which hold a posture of the support frames 1 inside the outer box 2.

As illustrated in FIG. 2, in each of the side portions of inner peripheral side portions corresponding to edge portions of the recessed section 5, support pieces 6 a to 6 d (examples of support portion 6) having cushioning functions for supporting the instrument A which is arranged within the recessed section 5 are protrudingly formed in a state of being freely bent (in detail, being freely folded inside the recessed section 5 on the bottom side) while having a base end portion as the fulcrum.

As illustrated in FIGS. 2 and 5, protrusion dimensions P1 of the support pieces 6 a and 6 d on a side of a short-side and protrusion dimensions P2 of the support pieces 6 b and 6 c on a side of a long-side are set to be greater than protrusion dimensions (the height) P7 of the flaps 7 of each the support frames 1 so as to be in oblique postures toward a central rear surface side while having the cushioning function in a state where the support frames 1 are accommodated inside the outer box 2.

Each of the support pieces 6 a to 6 d of the support frame 1 positioned on the lower side is configured to abut on an end portion of the instrument A from below so as to hold and support the instrument A. Each of the support pieces 6 a to 6 d of the support frame 1 positioned on the upper side is configured to abut on the end portion of the instrument A from above so as to support the instrument A. Accordingly, as the pair of support frames 1 are provided in postures where the front surface sides face each other, and the instrument A can be supported in a state of being interposed between the top and bottom of the support pieces 6 a to 6 d of the support frame 1 on the lower side and the support pieces 6 a to 6 d of the support frame 1 on the upper side. Moreover, since the support pieces 6 a to 6 d have the cushioning functions, it is possible to exhibit high cushioning performance and to stably support the instrument A.

The outer box 2 is configured to be formed of pattern paper such as corrugated paper and to have an open top-type box shape so that the pair of support frames 1 can be accommodated in superposed postures in which front surfaces of the pair of support frames 1 face each other.

A plurality of flaps 8 (examples of lids) which are able to block the top surface and are freely folded are protrudingly and respectively formed in the side portions of the upper edge portions of the outer box 2.

As illustrated in FIGS. 1 and 2, a width W2 of an accommodation space S2 inside the outer box 2 is configured to be equal to or slightly smaller than a width W4 of the base portion 4 of each of the support frames 1, and a depth D2 of an accommodation space S2 is configured to be equal to or slightly smaller than a depth D4 of the base portion 4 of each of the support frames 1.

A height H2 of the accommodation space S2 is configured to be equal to or slightly smaller than the height of the pair of support frames 1 in superposed postures in which the front surfaces thereof face each other (that is, the height twice the protrusion dimensions (the height) P7 of the flaps 7 of each of the support frames 1).

As illustrated in FIGS. 3 and 4, the inner bag 3 is formed of a soft synthetic resin made (an example of a resin made product) sheet which is elastically deformable. The inner bag 3 is configured to be freely mounted in one of the support frames 1 (an example of one or both of the pair of support frames 1) in a state where the instrument A is inner-packed and to be able to cause the instrument A inner-packed in a mounting posture with respect to the support frames 1 to be subjected to position-holding within the recessed section 5 of the support frames 1. As a synthetic resin material configuring the aforementioned sheet, a polypropylene-based resin having the high coefficient of extension is used.

An inner packing space S3 including an inserting and removing port 9 in one side portion on a side of the long-side is formed in an intermediate portion of the inner bag 3 in a longitudinal direction. The inner packing space S3 is configured to be formed by performing heat welding with respect to suitable places of two resin sheets in the front and rear (an upper covering portion 3A and a lower covering portion 3B). In this manner, the inner packing space S3 is formed between the upper covering portion 3A and the lower covering portion 3B.

Bag-like hooking portions 10 which can be respectively hooked over two flaps 7 (an example of two flaps 7 facing each other) on a side of the short-side of each of the support frames 1 is provided on both end sides in the longitudinal direction of the inner bag 3 on the rear surface side. The hooking portions 10 are configured to be formed by folding both end sides of the two resin sheets in the front and rear (the upper covering portion 3A and the lower covering portion 3B) in the longitudinal direction, and then, performing heat welding with respect to both sides of the folded portions.

The bag-like hooking portions 10 configure mounting portion for mounting the inner bag 3 in the support frames 1 and an attachment portion for attaching the inner bag 3 to the flaps 7 and 7 of the support frame 1 on the side of the short-side.

As illustrated in FIG. 5, a width (dimensions of the long-side) W3 of the inner bag 3 is configured to be equal to or slightly smaller than dimensions of an extension width W1 which is the sum of the width W4 of the base portion 4 of each of the support frames 1 and both the protrusion dimensions P7 of the flaps 7 and 7 on the side of the short-side.

In other words, as illustrated in FIG. 3, the inner bag 3 is configured to be mounted in the support frames 1 in a state where the inner bag 3 is pulled by a pair of the flaps 7 and 7 on the side of the short-side by covering the hooking portions 10 of the inner bag 3 so as to be hooked over with respect to the two flaps 7 and 7 in postures protruding toward the front surface side or a laterally outward side, and folding the flaps 7 and 7 toward the rear surface side from the state thereof.

Here, as the hooking portions 10 of the inner bag 3 are caused to cover the flaps 7 and 7 so as to be hooked thereover, the inner bag 3 can be mounted in the support frames 1 in a state where the upper covering portion 3A and the lower covering portion 3B are spread over the recessed section 5 of the support frames 1 and the periphery of the recessed section 5. Then, the posture in which the hooking portions 10 of the inner bag 3 are caused to cover the flaps 7 and 7 so as to be hooked thereover becomes an insertion posture of the inner bag 3. In the insertion posture, the instrument A is allowed to be inserted and removed with respect to the inner packing space S3. Moreover, as the flaps 7 and 7 are folded toward the rear surface side, the inner bag 3 is in a state of being pulled by the pair of flaps 7 and 7 on the side of the short-side. In this manner, as tensile force is applied to the peripheral side of the recessed section 5 with respect to both the upper covering portion 3A and the lower covering portion 3B, the posture of the inner bag 3 changes from the insertion posture to the mounting posture. As the posture of the inner bag 3 changes to the mounting posture, the instrument A is subjected to position-holding within the recessed section 5 of each of the pair of support frames 1 in a state where the upper covering portion 3A and the lower covering portion 3B are spread over the recessed section 5 of each of the pair of support frames 1 and the periphery of the recessed section 5.

As illustrated in FIG. 5, a width WS of the inner packing space S3 in a state where the instrument A is inner-packed is set to be smaller than a width W5 of the recessed section 5, and as illustrated in FIG. 2, at least a portion of an outer edge line 3 a of the inner packing space S3 in the inner bag 3 is configured to be positioned within the recessed section 5 of the support frames 1 in a state where the instrument A is inner-packed and is mounted in the support frames 1.

The entirety of the outer edge line 3 a of the inner packing space S3 in the inner bag 3 may be configured to be positioned within the recessed section 5 of the support frames 1 in a state where the instrument A is inner-packed and is mounted in the support frames 1.

In other words, as illustrated in FIG. 2, the packing tool T can pack the instrument A in a state where the instrument A is subjected to position-holding within the recessed section 5 of the pair of support frames 1 by the inner bag 3, and in a state where the instrument A is subjected to cushioning-support by each of the support pieces 6 a to 6 d of the pair of support frames 1.

Therefore, even when a significant impact force such as collision from dropping is applied to the outer box 2, a position-holding operation (a braking operation) performed by the inner bag 3 can prevent the instrument A from moving to the outer peripheral side (the support frame 1 side) where a collision force is significant, and a cushioning operation due to deformation (curved deformation or bending deformation) of the support portion 6 can be applied thereto together with a cushioning operation due to elastic deformation of the inner bag 3. According to the synergy effect thereof, it is possible to exhibit high cushioning performance so that the instrument A is less likely to break down.

Subsequently, description will be given regarding the packing procedure of the packing tool T having the above-described configuration. As illustrated in FIG. 3, the instrument A is stored in the inner packing space S3 through the inserting and removing port 9 of the inner bag 3. Then, the pair of flaps 7 and 7 of the support frame 1 on the side of the short-side are caused to be in postures protruding toward the front surface side (or the laterally outward side), and the bag-like hooking portions 10 of the inner bag 3 are caused to cover the flaps 7 and 7. Therefore, the hooking portions 10 of the inner bag 3 are respectively hooked over the flaps 7.

Thereafter, the pair of flaps 7 and 7 of the support frame 1 on the side of the short-side are folded toward the rear surface side, and then, the inner bag 3 is mounted in the support frames 1 in a state of being pulled by the pair of flaps 7 and 7 on the side of the short-side.

As illustrated in FIG. 1, the support frame 1 mounted with the inner bag 3 is subjected to insertion arrangement with respect to the outer box 2 on the bottom side. Thereupon, the other support frame 1 is subjected to insertion arrangement in a posture where the front surface side faces downward, and the instrument A is interposed between the pair of support frames 1.

Here, as illustrated in FIG. 2, the inner bag 3 is subjected to insertion arrangement with respect to the outer box 2 on the bottom side and is mounted in the support frame 1 which is positioned on the lower side. The inner bag 3 is provided in a state of spreading over the front surface side of the support frame 1 so as to cover the entirety thereof. Accordingly, as the other support frame 1 is subjected to insertion arrangement in a posture where the front surface side faces downward, the inner bag 3 is interposed between the pair of support frames 1 on the front surface side. Therefore, the inner bag 3 is likely to be maintained in a tensile state when the pair of support frames 1 is accommodated in the outer box 2.

Then, each of the flaps 8 of the upper edge portion of the outer box 2 is folded inward so as to block the top surface portion thereof. Thereafter, the postures of the flaps 8 are fixed by using fixing tool such as tape, and packing of the instrument A thereby ends.

Second Embodiment

In the first embodiment described above, a pair of the support frames 1 are provided, and the pair of support frames 1 are accommodated in the outer box 2 while being in postures where the front surface sides thereof face each other. In place of the above configuration, in a second embodiment, as illustrated in FIGS. 6 and 7, one support frame 1 is provided, the one support frame 1 is accommodated in the outer box 2, and a cushioning member 21 having a cushioning function is arranged in an empty space above the support frame 1.

The second embodiment is configured to include a bag-like member which is the cushioning member 21 exhibiting the cushioning function as gas is enclosed in a gas enclosure space 22. The cushioning member 21 is included integrally with the inner bag 3. For example, a gas enclosure space forming sheet 23 is additionally arranged on the upper side of a sheet which becomes the upper covering portion 3A of the inner bag 3, and the sheet which becomes the upper covering portion 3A and a predetermined place of the gas enclosure space forming sheet 23 is subjected to heat welding in a series manner, thereby forming the gas enclosure space 22. Then, gas such as air is supplied to the gas enclosure space 22 from a gas supply unit which is provided in the end portion or the like of the gas enclosure space forming sheet 23, thereby filling gas in the gas enclosure space 22. Here, it is preferable that the gas enclosure space 22 is formed in a state of spreading over the entirety of the recessed section 5 of the support frame 1 and the periphery of the recessed section 5 in a planar view.

As the packing procedure in the second embodiment, first, similar to the first embodiment (refer to FIG. 3) described above, the instrument A is stored in the inner packing space S3 through the inserting and removing port 9 of the inner bag 3, the pair of flaps 7 and 7 of the support frame 1 on the side of the short-side are caused to be in postures protruding toward the front surface side (or the laterally outward side), the flaps 7 and 7 are covered with the bag-like hooking portions 10 of the inner bag 3, and thereby the hooking portions 10 of the inner bag 3 and the flaps 7 are respectively hooked. Consequently, the inner bag 3 is mounted in the support frame 1 in the insertion posture. Thereafter, the pair of flaps 7 and 7 of the support frame 1 on the side of the short-side are folded toward the rear surface side, and the inner bag 3 is mounted in the support frame 1 in a state of being pulled by the pair of flaps 7 and 7 on the side of the short-side. In other words, as a tensile force toward the peripheral side of the recessed section 5 is applied to both the upper covering portion 3A and the lower covering portion 3B, the posture of the inner bag 3 changes from the insertion posture to the mounting posture. As the posture of the inner bag 3 changes to the mounting posture, the instrument A is subjected to position-holding within the recessed section 5 of the support frames 1 in a state where the upper covering portion 3A and the lower covering portion 3B are spread over the recessed section 5 of the support frame 1 and the periphery of the recessed section 5.

Then, as illustrated in FIG. 6, the support frame 1 mounted with the inner bag 3 is subjected to insertion arrangement with respect to the outer box 2 on the bottom side, gas such as air is supplied to the gas enclosure space 22 from the gas supply unit (not illustrated), and thereby gas fills the gas enclosure space 22 which is formed in a state of spreading over the entirety of the recessed section 5 of the support frame 1 and the periphery of the recessed section 5. Accordingly, as illustrated in FIG. 7, the upper side of the instrument A inner-packed in the inner bag 3 and the front surface side of the support frame 1 are covered with the gas enclosure space 22, and each of the flaps 8 of the upper edge portion of the outer box 2 is folded inward so as to block the top surface portion. Thereafter, the postures of the flaps 8 are fixed by using fixing tool such as tape, and packing of the instrument A thereby ends.

However, on the contrary, the hooking portions may be provided in both the end portions of the inner bag 3 in the short direction, and the hooking portions may be hooked over the two flaps of the support frame 1 on the side of the long-side.

(8) In the above-described embodiment, as the packing procedure, first, the instrument A is stored in the inner packing space S3 through the inserting and removing port 9 of the inner bag 3, and subsequently, the inner bag 3 having the instrument A stored therein is mounted in the support frame 1. Instead, first, the empty inner bag 3 in which no instrument A is stored in the inner packing space S3 can be mounted in the support frame 1, and subsequently, the instrument A can be inserted into the inner packing space S3 through the inserting and removing port 9 and can be stored therein with respect to the inner bag 3 mounted in the support frame 1. In this case, as the bag-like hooking portions 10 of the inner bag 3 are caused to cover the flaps 7 and 7, the hooking portions 10 of the inner bag 3 and the flaps 7 can be respectively hooked so that the inner bag 3 can be mounted in the support frame 1 in the insertion posture. Then, when the instrument A is stored in the inner bag 3 in the insertion posture, the pair of flaps 7 and 7 of the support frame 1 on the side of the short-side are in the posture protruding toward the front surface side (or the laterally outward side) so that the inserting and removing port 9 is likely to be open wide. Thus, the storing work can be easily performed.

(9) In the above-described embodiment, the outer box 2 is a target in which a pair of support frames 1 or one support frame 1 is accommodated. However, without being limited to the outer box 2, the target may favorably be an outer packing body which covers the periphery of the support frame 1, and the pair of support frames 1 or the one support frame 1 can be accommodated in the outer packing body. In this case, for example, it is suitable that an outer packing body having the cushioning function is used. Otherwise, it is suitable that the pair of support frames 1 or the one support frame 1 is accommodated in the outer packing body in as state of being covered with a cushioning material.

(10) In the above-described first embodiment, when the inner bag 3 is mounted in the support frame 1, the inner bag 3 is mounted in the support frame 1 which is positioned below. Instead, for example, one hooking portion 10 of the inner bag 3 can be hooked over one flap 7 of the support frame 1 on the side of the short-side positioned below, and the other hooking portion 10 of the inner bag 3 can be hooked over the other flap 7 of the support frame 1 on the side of the short-side positioned above. Accordingly, the inner bag 3 can be mounted in a state of spreading over the support frame 1 positioned below and the support frame 1 positioned above. Moreover, both of the hooking portions 10 of the inner bag 3 can be hooked over the two flaps 7 of the support frame 1 on the side of the short-side positioned above so that the inner bag 3 can be mounted in the support frame 1 which is positioned above.

(11) In the above-described second embodiment, the cushioning member 21 which is arranged in the empty space above the support frame 1 is configured to be formed of a member exhibiting the cushioning function by enclosing gas in the gas enclosure space 22 which is formed of the gas enclosure space forming sheet 23. However, instead, for example, an elastic member such as a sponge can fill the empty space as a cushioning member so as to cover the upper side of the instrument A inner-packed in the inner bag 3 and the front surface side of the support frame 1.
